SAFE.

SPECIFICATION forming part of Letters Patent No. 405,562, dated June 18,1889,

Application filed August 13, 1888. $erial No. 282,487. (No model.)

To (all whom it 71mg concern:

Be it known that l, PHINEAS F. KING, a citizen of the United States, anda resident of Cincinnati, in the county of Hamilton and State of Ohio,have invented certain new and useful Improvements in Burglar-ProofSafes, of which the following is a specification.

My invention is an improved means of constructing burglar-proof work,such as safes, vaults, and other secure receptacles for storing andprotecting valuables.

It consists, primarily, in means for constructing the skeleton of thestructure and so forming the interlocking joints that the parts areentirely secured togetherfrom the inside, and the possibility ofstripping the plates or wedging the joints apart is precluded.

It also consists in certain features of construction calculated toreduce the labor of fitting and add to the strength of the structure,all of which will be first fully described in connection with theaccompanying drawings, and will then be particularly referred to, andpointed out in the claims.

Referring 110w to the drawings, in which like parts are indicated bysimilar reference-letters wherever they occur throughout the variousviews, Figure 1 is a horizontal section of a vault constructed accordingto my invention. Fig. 2 is a detail sectional view of the interlockingedges of the wall-plates separated. Fig. 3 is a similar view of theplates secured together by an interior lap-plate. Fig. at is a similarView of the lock-joint, but with the locking-tonguc formed inward fromthe edge, and the groove and rabbet upon the edge of the opposite plateformed to match and admit of tightening-screws being used upon each sideof the tongue. Fig. 5 is a transverse horizontal section of the skeletonbefore the plates forming the walls are secured in place. Fig. 6 is aperspective view of one corner of the angle-bar frame which forms thefront and rear frames of the skeleton, and one end of one of theangle-bars which connect two angle-bar frames to form the skeleton ofthe safe or vault, the frame and connecting -bar being disconnected toclearly indicate the details of construction of each. Fig. 7 is a planview of a part of one of the angle-bars grooved and notched preparatoryto bending at the notched portions to form the angle-frame, one cornerof which is shown in Fig. 6. Fig. 8 is detail perspective view of onecorner of one of the plates which form the walls of the safe.

The skeleton of the vault is formed of two frames A, formed of bentangle-bars, and four straight angle-bars B, which connect the two framesat their corners. The angle-bars and angle-bar frames are preferably oflaminated steel and iron.

To form the frames A, angle-bars of the proper length to make frames ofthe desired size when bent are first planed off upon their inner edges,forming rabbets a, and are then grooved at a, after which one web isnotched at a at the four points at which the bar is to be bent to formthe rectangular frame. The straight an gle-bars are similarly rabbetedand grooved upon the inside edges. Each end of the bars 13 istransversely grooved at Z), forming the reduced angular tongue Z), tofit into the groove to, the groove 1) fitting the rabbets a upon theinside of the angle-frame A. The ends of the bars thus match with thecorners of the angle-bar frame and make a smooth finish inside andoutside.

The angle-bars B are firmly secured to the angle-bar frames by steelscrews passing through the holes b in bars B into the screwtapped holesa in the angle-bar frames.

After the frame or skeleton of the safe or vault is formed by unitingtwo frames A by four angle-bars B the wall-plates C, Fig. 8,

which have their edges grooved at c and formed into tongues c to matchinto the grooved and rabbeted edges of the angleframes and bars, areinserted in place from the inside and secured in place by steel bolts D.

If the vault or strong box is of such size as to require more than oneplate, the meeting edges of the plates are matched together in themannershown that is, the meeting edges of the plates are grooved andrabbeted upon the opposite faces, so that the outer and inner faces ofthe walls present smooth even surfaces. The plates are secured togetherand to the angle-frames by steel screws pass ing through the thinn erbottoms of the grooves into the tongues, as seen in Fig.1; or where theinner steel lap-plates are used, as seen in Fig. 3, the screws may bepassed through the inner steel plate into any part of the outer plates.The jamb-plates or stiles for the door are secured to the front framethe same as the plates.

It is evident that the walls of my vault or strong box may be made ofany desired thickness by using more or less plates upon the inside, andit .is also evident that the grooves and rabbets may be reversedthat is,formed upon the opposite sides of the angle frames, bars, andwall-plates from those shown in the drawings. I11 fact, I find it bestin constructing large vaults according to my invention to employ theangle-bar frames at top and bottom of the structure, and employ thestraight angle-bars for the upright corners. In this case I also preferto rabbet and groove the lower or horizontal web of the lower frame uponthe outside, so that the inner plates may be more readily introduced andsecured, after which the bottom of the vault is secured in place and thecaster-frames, when such areused, are secured from the inside, thusoverlapping the joints and giving additional strength to the lowercorners.

The meeting ends of the angle-bar frames understood, of course, thatafter the parts are properly dressed and fitted together, the screwholesbored and tapped, the parts are again straight angle-bars B, similarlygrooved upon their inside faces, and transversely rabbeted and groovedat b b to match into the corners of frames A to form the skeleton of aburglarproof safe, substantially as hereinbefore set fortlr- 2. In aburglar-proof safe, the combination, substantially as specified, of theangle-bar frames tongued and grooved near their edges, as shown, thestraight angle-bar pieces similarly tongued and grooved, and alsotongued and grooved transversely at each end to match the corners of theframes, and the wall-plates for the body of the safe having their, edgesformed to interlock with the angle-bar frames and their connectingangle-bars, for the purpose set forth.

The eombination, in a burglar-proof safe, of the angle-bar frames, thestraight anglebars connecting twoof said frames, and the wall-plates Cand interior lap-plates, said frames, angle-bars, and plates 0 havingoverlapping and interlocking edges, whereby the parts may be securedtogether from the inside and wedging or separation of the partsprevented.
